The Fluid Components FS10A is a universal flow monitor and switch specifically designed for gas and liquid process analyzer sampling systems. 

The FS10A is a fast responding, highly repeatable sensor which installs easily into a standard tube tee fitting or new SP76 (NeSSI) modular manifold.

The FS10A utilizes proven thermal-dispersion flow measurement technology with FCI proprietary equal mass sensing to achieve outstanding sensitivity and repeatability. The instrument’s wetted parts are superior corrosion-resistant 316L stainless steel with Hastelloy-C sensor tips. An optional all Hastelloy-C sensor element is also available.

The sensor element has no moving parts to foul, clog or maintain which ensures continuous reliability and no maintenance costs. There are no cavities, orifices or dead-legs to trap or contaminate samples which preserves sample integrity and faster system sampling times.

FS10A electronics are packaged in a rugged, fully-sealed, aluminum housing which provides exceptional protection and long-life under all process conditions.

The electronics can be integral mounted with the sensor element resulting in unibody, self-contained unit (FS10A-1, FS10A-2) or the electronics can be separated from the sensor for remote mounting (FS10A-3, FS10A-4). The remote configuration is useful when sensor installation area is subjected to high temperatures, or to mount the front panel and display in a more accessible location.
